PLOW.

Serial No. 771,753.

To all ii /mm, it may concern lie it known that l, Nnwma. Sannnns,citizen oi the llnited States, residing at (lhat1- tanooga, llennessee,have invented certain new and usetul Improvements in llows, oli whichthe ilollowing is a spccili ration.

h lly invention relates to gang plow t'rames ol that class in wnieh onemain trame member is provided with a plurality ol? harms, each connectedto the main frame member and iarrying a itnrrow opening device. t liiscrmstructimi is shown, among others, in Letters Patent of the UnitedStates, granted to me in 190", and nmnbered t ofidiiiii. in this, as inmy present invention, the l'urrow (peeing devices are in the term otdisks.

My invention hereinafter described consists oli a detail of constructionin the disk carrying beams.

it is illustrated in drawings, in which t- Figure 1. shows in plan, themain trame lueinbe and beams at my improved plow; illustrates theadvantage at my improminent orer the old form.

in olows of this class itis necessary that, in addition to the 'turrowopening devices, the front beam must, carry the front supporting wheel.and that the rear b am must carry the rear supporting whee and theplowman. This puts special strain upon these beams as compared with theintermediate beams and renders necessary a tiruier connection with themain frame member by means of longer area of contact and more bolts,This increased firmness of attaelunent is amply provided tor in thetrout: beam, without change in its :t'orm, by mere extension as there isanipl i space at the trout end of the main frame member for greater lapof the front beam and tor more bolts than is necessary tor theintermediate beams which carry only disks. For varying conditions it isnecessary to ixpand and :ontract this arrangement of beanis in order toout either wide or narrow t'urrows, the minimum in usual p actiee beingabout six inches. In order to get the beams close enough together forthis purpose, it is necessary to illttli a. sharp angle where the beamleaves the main frame member, and it is also necessary that the troutends of all the b 'ams, except the trout beam, should be short, allowingfor only two bolts on the usual size oil main frame member. This allowsthe front end of the harm to go near the aeeonipanying enough to thenext beam ahead and also allows the forward end (it the next b am behindto come up near enough to cut a minimum width of :liurrow. 'lhis shapeoil beam, however, does not admit of a longer bearing of rear beam uponthe main frame member, which is necessary tor requisite strength anddoes not; admit of an incraised number of bolts for the same purpose. Ihave found that I can accomplish this by extending the front part of therear beam farther back, making a sharp angle o' a short curve in orderto bring the rear part of the rear beam in proper relation to the otherbeams, so that: unitorm furrows will be cut. This shape of beam cannotbe used for the other beams ol, the plow, because this shape will notallow the next lJBttlll back to come up close enough in order to cut asnarrow a turrow as is necessary.

Beams like the two front beams here shown are described in the patentabove mentioned and have been in use for many years. The addition (itthe rear beam, of the shape shown, to this (aimbimition enables the plowto cut: narrower tturrows than before. For instance, with the usual sizeof material it was not possible to out less than eight inch furrowsbet'ore, while this arraugenlent makes it possible to cut six inch 1' ll rrows.

l-Zelerring more particularly to the drawings, the main frame member isixnlicated at A. An intermediate beam which carries only a disk ismarked 7), and the r m.- beam, which rarries, in addition to theordinary disk, a supporting wheel and drivers seat, is marked 7). The st'aight part oi. the interniediate beam which b ars upon and is bolted tothe main beam, is marked 2. It is shortened, so that in its mostadvanced position (for the narrowest tin-row) its Forward end 3 abuts atthi angle made by the next; beam and the main frame member. lint thislength is snllicient tor the bolts of the h aims 'arrying only disks.

To give the greater bearing, the rear beam 7) is formed with a. singlebend (omitting the straight middle part tormerly used), as shown. at t.This is practically an extension rearward ot the straight part of thebeam which laps upon the main team, and thus extended rearward it givesthe needed increase in the bearing surface, and the space for increasednumber of bolts required for the gr aiter strain. By reason also of themore obtuse angle it brings the rear part of the beam and its disk intoproper relation to the other beams and disks, and makes the furrowsequal.

Fig. 1 shows the plow in its expanded form and Fig. 2 in its contractedform. It is plainly shown by the full lines that the forward orattaching part of the rear beam Z) admits more bolts than. theintermediate, with the same spacing, though its front end abuts the bentportion of the preceding beam.

If the beam 7) were of the old form with two bends, with its attachingportion long enough for three bolts, as indicated in dotted lines, thenit would not be possible to adjust it far enough forward by the spacebetween 7 and 8 to bring its disk carrying portion in proper position.

In practice the number of bolts used is limited by the space betweenthem, on account of the space required for the nuts and V a suitablewrench to turn them. The position of the bolt holes is indicated by thecross lines.

I claim as my invention In a gang plow of the class described, a

main frame member, one or more beams havln two bends or an les boltedthereto and a rear beam having an extended partlapped upon and bolted tosald frame mem- Copies of this patent may be obtained for five centseach, by addressing the Commissioner of Patents. Washington, D. C.
